Analytical Techniques for Identifying Mineral Scales and Deposits
A number of methods may be employed to characterize mineral scales (i.e., calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride, and so on) and deposits (i.e., rust, clay, zinc oxide, and so on). Some of these methods are listed in Table 21.1, along with the type of information and their advantages and disadvantages.
